Abstract

For image processing with a simplified low-cost device, a main CPU (31) issues a draw command to instruct a rendering engine (41) to perform convolution filtering. In response to this command, the rendering engine (41) performs convolution filtering by overwriting the drawing area repeatedly with the value of the pixel data of a texture area of an image memory (43) multiplied by a convolution filter coefficient.
